If money wasn't an issue, I'd contract a company to make my own.
Or possibly build a set top box, to be more realistic...but I don't really know the Linux support of various distros for different PCI cards, and their use in set top boxes. I'd have to research it. (Please no one reply to me mentioning Windows...)
I've actually been trying to decide on a receiver, and it seems nearly impossible. You have to debate the features with the reviews, and I wonder if any receiver actually meets my dream specifications.
Required: DiSEqC 1.2, Blind Scan (obviously), DVB-S, DVB-S2, MPEG2, MPEG4, USB Hard Drive Support, HDMI/DVI with sub/closed captioning support
Preferably: DiSEqC 1.3, 4:2:2, h.264, 1080p, FAST Blind Scan, Linux, fast processor, Ethernet, Streaming to a computer, playback of vids/music from computer, internal 3.5 hard drive, DVD Burning
Dreams: Split Screen / Multi Screen with 4 or more signals (that would be AWESOME!!! Could have my own version of Superman's news feeds), BluRay/DVD burner, able to play online videos and streams...that's all I can think of now...
I was looking at the DreamBox DM8000 HD...which is literally a dream box...but I don't know if it's actually any good. Just looked pretty cool with all of it's overpriced features.
Edit: Stogie, why do you suggest the Opensat for people that aren't really into sports?
